Paragraph 12
Nothing in this Schedule shall—
operate in derogation of any provision having the force of law by which the consent of any government department is required for the erection of a bridge over any watercourse, or by virtue of which any powers are exercisable by any government department in relation to such a bridge; or
impose any liability on the Ministry in respect of the erection, placing, alteration or repairing of any structure; or
apply to any works under the control of a harbour authority or conservancy authority, or maintained under any statutory provision;
but, where any work under the control of any authority mentioned in paragraph ( c), or of any person exercising powers under any statutory provision, is likely to interfere in any way with the proper functioning or maintenance of, or of the carrying out of any works on, a watercourse, or with the passage of fish, that authority or person shall consult with the Ministry for the purpose of ensuring that, so far as possible, any such interference is avoided.
